A student sits at rest on a piano stool that can rotate withoutfriction. The moment of inertia of the student -stool system is4.1kg.m2. A second student tosses a 1.5-kg mass with aspeed of 2.7m/s to the student on the stool, who catches it at adistance of 0.40m from the axis of rotation. What is the resulting angular speed of the student and the stool?
